Esther Fitzgerald · Answer 1

34.32 sq feet

Step-by-step explanation:

it is about finding the total surface area. Since it is a rectangular prism, we will have 2 identical sizes of front and back, 2 identical sizes of top and bottom, and 2 identical sizes of right and left.

therefore

front = 2.2 x 3.3 = 7.26

top = 3.3 x 1.8 = 5.94

right = 1.8 x 2.2=3.96

total SA = 2 (7.26 + 5.94 + 3.96) = 34.32
